Does anyone have any info on how I can replace my computer controlled Rochester Qjet on my 1981 corvette with a standard Qjet ? I understand that the Distributor also has to be replaced. Any info would be greatly appreciated , especially what Qjet to use( can I use one from a 1980 or 1979 corvette ) and also can I use just a stock HEI distributor with a vacuum advance. Thanks....... :)
